With regard to the divalent substituents described in the claims, e.g., Q and W₁, these divalent radicals are defined as α--R_(i) :β--R_(j), where R_(i) represents a substituent of the divalent moiety of the alpha configuration with respect to the cyclopentane and R_(j) represents a substituent of the divalent moiety of the beta configuration with respect to the cyclopentane ring. Accordingly, when Q is defined as α--OH:β--R₈, the hydroxy of the Q moiety is in the alpha configuration, i.e., as in prostacyclin, and the R₈ substituent is in the beta configuration. Not all carbon atoms to which such divalent moieties are attached represent asymmetric centers. For example, when both valence bonds are to hydrogen (e.g., W₁ or Q is α--H:β--H), then no asymmetric center is present.
